Campagnolo Veloce BB vs Miche Primato

I got myself a new Campy Veloce BB for my conversion, but the chainline is 43.5 mm --measured with a caliper, and my back hub is an Ambrosio one which gives a 42mm chainline (the frame is steel and springs to 120mm from 126).

I could live with some chainline offset but:

1) is there anything I can do to the Campy Veloce to improve the chainline (I dunno, like whack it with a hammer)?

2) given I'm not gonna change cranks, would a Miche Primato fit them (they obviously fit the Campy). And should I go for a replacement BB with Miche, should I get the 107 or the 111 version? My BB shell is 68mm if that helps.

BTW, I was told I could expect something like two years daily use out of a Veloce BB, how would the Miche compare?

1.5mm will not have any great impact on your chainline, just fit the veloce and the miche cranks and ride the bike, it will be fine. The miche bb is not the best so avoid it.

Well, I read many opposite reviews of the Miche, and for 13 quid it might be worth the try. In addition, I find the transmission too noisy now, so I'd like to either sort the Veloce bb somehow or to change it.

rode this same set up everyday for 2 years pretty much works fine.

on a 3/32 or or on a 1/8 chain? Mine is 1/8, and quite noisy now!

road it on both combos actually depending on what rings/cogs i was running.
i think most of the time i ran 3/32 everything.

Miche BB's are crap. Campag are usually good and despite being cheap, the Veloce is no exception.

On the Veloce, is the drive side cup the cup that's fused to the axle/bearing unit? Is feasible that you could unscrew it out by half a mil or a mil (as required) and use a Velosolo spacer? Or is that massively unsafe?

Can't remember if it's the drive side or not that's attached to the axle.

Sounds safe, though... I imagine there's enough thread?

Are you trying to push the driveside crank further out to clear the stays? If so, remember that you'll shift the whole axle along so it may affect clearance on the non driveside.

I could just be talking shite. What's your problem then?

I'm fine, just suggesting a potential chainline finetuning option, for when 109/111/115 don't quite cut it. Pretty ghetto solution, tbf

What hub? On my Phil I've used 109 and 111 and they are both just as good as each other.

Used 115 once as I had to (C Record Pista cranks - tight Q-factor) and the chainline was pretty out but it still worked well enough for me to ride it brakeless every day.

I'm in a well chatty mood today. I feel sorry for all my friends at West's later...

I'm currently on Miche hubs, my chainline's perfect with a 115mm axle, but that's with shaved Campag Strada cranks.

Mental.

I run a Miche BB and theres fuck all wrong with it, especially for £11 which is what i bought mine for. If installed properly you'll have no issues whatsoever.

For a 68mm shell a 107 Miche BB gives a perfect chainline, happy days :-)

I run the same (but with formula hubs) due to clearance issues. It's not perfect but not as bad as I was expecting having run the same setup on a previous bike with 111 mm bottom bracket, certainly livable.

Used a veloce bottom bracket for around 2 years, no problems.

Nope, it's the other way around...

the problem is that I need to push the driveside towards the bike by 1.5mm, not further away (or I'd get a chainline at the crank of 45mm!). I cannot add spaces driveside, not flip the hub, so, aside from shawing something off either the crank or the bb I dunno what to do (aside a different bb)!

Spacer behind the sprocket?

Do you mean a spacer behind the fixed cog on the wheel hub? I suspect I might die if I do that...

Just get the right bottom bracket. It'll save you a lot of trouble in the future.

Bodges are never good unless done by me.

Why? as long as you have sufficient thread for a locking I see no problem.

Truth.

Had the same problem a while back... I agree the Compag is a far far far better bb, but I fitted the Miche, giving me a perfect chainline instead. Silent.

No issues at all with the Miche, as in it hasn't exploded or anything. If/when it does, I'll put another one in (unless I can find, and afford, a better quality 107mm ISO bb). I just feel a lot more happy when the chain's straight.

The bearings were gone on my old Miche BB. So I'm installing a new Miche BB right now, .. but i've just tightened the cups and it seems that the turning of the spindle by hand is particularly un-smooth, sort of gritty and difficult to spin... does any one have any idea what is going on? before i put it in the action seemed to be perfectly smooth, so i'm a bit perplexed, it feels less smooth that the one i just took out!...\

any clues?
